Git commit 8e45efdc9dd410bdca4ddd795b5e403c14d5dc56 by David Edmundson. Committed on 24/02/2021 at 09:35. Pushed by davidedmundson into branch 'master'. [kcms/activities] Fixup DBus path usage In a code cleanup the path name got corrupted. The use of macros obfuscates what can be done with a simple string. This code takes it back to what's helpful. Whilst we're at it, ResourceScoring was using QDBusInterface and string based method names. This means syncrononous calls, and also can get easily broken in future porting, so this is switched to using the generated interface.
